Objective: The objectives of this study were to investigate how many patients use direct access and to establish whether these patients have a different profile than referred patients.
Methods: Electronic health care data from the National Information Service for Allied Health Care (LiPZ), a nationally representative registration network of 93 Dutch physical therapists working in 43 private practices, were used.
Results: In 2006, 28% of the patients seen by a physical therapist came by direct access. Patients with non–further-specified back problems, patients with nonspecific neck complaints, and higher-educated patients were more likely to refer themselves to a physical therapist, as were patients with health problems lasting for less than 1 month. Younger patients made more use of direct access. In addition, patients with recurring complaints more often referred themselves, as did patients who had received earlier treatment by a physical therapist. Patients with direct access received fewer treatment sessions. Compared with 2005, there was no increase in the number of patients visiting a physical therapist.
Limitations: Data came only from physical therapists working on general conditions in general practices. Severity of complaints is not reported.
Conclusions: A large, specific group of patients utilized self-referral, but the total number of patients seen by a physical therapist remained the same. In the future, it is important to evaluate the consequences of direct access, both on quality aspects and on cost-effectiveness.

The current study was conducted to investigate the effects of the first year of direct access. Internationally, direct access has been under discussion for some time, and it is established in Australia, New Zealand, most states of the United States, Canada, and the United Kingdom.2–4 However, direct access is not uniformly implemented, and reimbursement conditions vary.5 In the Netherlands, direct access to physical therapy means that evaluation and treatment by a physical therapist is possible without referral by a physician. Most Dutch health care insurers reimburse physical therapists for direct access without restrictions.
Both proponents and opponents of direct access are found in the Netherlands. Arguments in favor of direct access to physical therapy can be divided into advantages for patients, physical therapists, and physicians. The greater freedom of choice and improved and faster access to physical therapy are seen as the main advantages for patients.6–8 Furthermore, direct access both acknowledges and increases the professional responsibility and challenge for physical therapists, as they now make independent decisions about further patient management. Finally, direct access decreases the workload of general practitioners (GPs) because a proportion of patients with musculoskeletal disorders or complaints will go directly to a physical therapist without consulting their physician first.6 Before 2006, 90% of patients of physical therapists in the Netherlands were referred by their GP and 10% were referred by a medical specialist.9
However, opponents feared missed pathology due to physical therapists supposed inadequate knowledge of diagnostic strategies and decreasing communication between GPs and physical therapists.8,10,11 Furthermore, health care insurers especially feared an increase of patients receiving physical therapy after the abolition of the gatekeeper role of the GP. Therefore, several studies were performed before direct access was legalized. Following a feasibility study in 2001,12 a pilot study was carried out in a specific region in order to acquire actual experience with direct access.13 This pilot study made clear that direct access leads to satisfaction not only for patients but also for physical therapists and GPs. Based on the findings of the feasibility study and the pilot study, it was recommended that physical therapists should obtain additional education in diagnostic decision making before introducing direct access.14 Although physical therapists in the Netherlands are not trained to make a medical diagnosis, they should be able to make a proper differential or physical therapy diagnosis through adequate interpretation of signs and symptoms. Following the recommendations, Dutch physical therapists completed mandatory postgraduate education in 2005. The most important topic of this education was the ability to detect relative and absolute contraindications for physical therapy, the so called "yellow flags" and "red flags." Furthermore, formalization of the communication and cooperation between physical therapists and GPs was an important issue.
Direct access to physical therapy has been possible for more than a year now, and thus it is time to evaluate the initial results. The following research questions were addressed in this study:

For the present study, the network consisted of 43 practices with 93 physical therapists. A relative over-representation of male therapists was found. For age, year of graduation, hours working, type of practice, region, and urbanization, no differences were found between the therapists in the LiPZ network and the Dutch population of extramurally working physical therapists (Tab. 1).

Data Analysis
Data were analyzed with SPSS 14.0.* For a number of cases, information on the mode of access was missing, mainly due to a delay in the development of the software. We checked whether these missing data could have biased the results. Patients for whom mode of access (referred versus direct access) was known were compared with patients for whom this information was missing. In this analysis, sex, age, level of education, diagnosis, duration of the health problem, whether it was a recurring health problem, and earlier treatment were taking into account using chi-square tests.
To analyze differences in characteristics between patients who were seen by a physical therapist via direct access and patients who were referred by their physician, multivariate logistic regression (method enter) was carried out. Before performing this regression analysis, correlations among all factors that were to be included in the model were calculated in order to check for covariation. For the differences in the number of treatment sessions between the 2 patient groups, multivariate linear regression (method enter) was used. To analyze the difference in treatment sessions, only data from patients who received further treatment after the initial intake were used. Data from patients who received their initial screening within a time span of 30 days until the end of the registration period and who had not yet received treatment were left out the analysis. This criterion of 30 days was chosen because it is assumed that, in most cases, treatment will start within 30 days after screening. Before this period has finished, it cannot be decided whether patients have been treated.
A number of missing sets of data for the regression analyses emerged because not all factors taken into account to investigate the differences between patients using direct access and referred patients were filled in completely by the physical therapists. Data were missing for level of education, duration of the complaint, recurrent health problem, and earlier treatment. To check whether these missing data biased the results, regression analysis was carried out with 2 dummy groups: unknown level of education and unknown duration of complaint. Furthermore, the categories of recurrent health problem and earlier treatment were changed from "yes" versus "no" to "yes" versus "no/unknown." Differences in discharge data were analyzed using chi-square tests, followed by Mann-Whitney U tests to locate the differences. Treatment outcome was not filled in for every patient. Data also were analyzed by including these missing data into the category no/unknown" in order to check for bias. On the outcome measure, differences in the patient population between 2006 and 2005 were investigated with chi-square tests for the characteristics of the patients and with a paired t test for the volume.

Demographic and Health Characteristics of Patients Using Direct Access
No significant covariations larger than 0.34 were found among the several factors that were entered into the regression models. Patients who had referred themselves differed significantly from patients who were referred by their physician, based on age, level of education, and the characteristics of their health problem (Tab. 3). The type of health problem and the patients level of education were found to be the strongest predictors of use of direct access. Patients with non–further-specified back problems (coded in ICPC terms), patients with nonspecific neck complaints (coded in ICPC terms), and higher-educated patients were more likely to refer themselves to a physical therapist compared with patients with other health problems and lower-educated patients. Furthermore, patients with health problems existing for less than 1 month opted more often for visiting a physical therapist without consulting a physician first compared with patients with conditions that lasted for longer than 3 months. Younger patients were more likely than older patients to make use of direct access. Patients with recurring health problems referred themselves more often compared with patients with a new health problem. Patients who had received earlier treatment by a physical therapist also referred themselves more often compared with patients who had not been treated previously by a physical therapist. The same results were found when the data were analyzed with a correction for missing data.

Change in Volume and Type of Patients Among the Patient Population
To check whether the patient population has changed after the introduction of direct access, data from 2005 were compared with data from 2006. In 2006, there was no increase in the total number of patients treated by physical therapists (P=.608). The composition of the patient population, however, changed slightly. In 2005, one third (38.6%) of the patients had complaints that existed for less than 1 month, whereas in 2006, 40.8% of the patients had these short-lived problems (P<.01). Smaller differences were found for the variables of sex, health conditions presented, the number of recurrent complaints presented, and the number of patients who received earlier physical therapy treatment. In 2005, 41.8% of the patients were male; this percentage diminished to 40.1% in 2006 (P<.01). In 2005, 12.2% of the patients had nonspecific low back pain compared with 13.2% in 2006 (P<.01). The number of patients with recurrent problems increased from 33.2% in 2005 to 34.9% in 2006 (P<.01), while the proportion of patients who received earlier treatment increased from 45.2% to 47.1% (P<.01).

Yet, in the first year after the introduction of direct access to physical therapy, more than one quarter of all patients made use of this mode of access. Apparently, freedom of choice, which was seen as an important advantage of direct access for patients, satisfies a need. The proportion of patients found choosing direct access exceeds expectations, and data from international studies, where figures for direct access ranging from 9% in Massachusetts19 to 22% in Scotland,20 have been reported. The low rate of direct access found in Massachusetts was explained by employer policies and lack of reimbursement.19 Holdsworth et al20 reported the results of a trial of 26 practices. In the Netherlands, direct access was introduced nationally and was accompanied by an extensive publicity campaign. Furthermore, most insurance companies reimburse for direct access without further restrictions. Therefore, broader acquaintance of the public and better reimbursement conditions may explain the relatively large percentage of direct access found in the present study.
Patients who referred themselves for physical therapy appeared to differ from patients who were referred by their physician, a finding corresponding with international literature on direct access.3,20 In the present study, patients who saw a physical therapist via direct access were more likely to be younger and higher educated compared with patients who were referred by their physician. Furthermore, patients with aspecific complaints of the spine, patients with recurrent complaints, and patients who had been treated before by a physical therapist made more use of direct access. Possibly due to tradition, and based on a long-standing relationship, older patients have a greater reliance on their GP than younger patients. In addition, older people more often have comorbidities, possibly increasing the need to visit their GP. Higher-educated clients may be better able to inform themselves about their symptoms and available health care, and they, therefore, may be more inclined to make their own decisions regarding treatment. Knowledge about symptoms and about the specific competence of the physical therapist also could explain why patients with recurrent problems referred themselves more often in comparison with patients who had no earlier experience with physical therapy. Finally, an important difference was found for the duration of the presented health care problems. Patients who made use of direct access more often had complaints existing for less than 1 month.
The patients with direct access distinguished themselves not only by their demographic characteristics and features of their health problems but also by their treatment. Patients who saw a therapist via direct access received fewer treatment sessions than patients who were referred by their physician and their treatment goals, according to their physical therapist, were more often fully achieved. This finding is similar to those of Holdsworth and Webster3 and Mitchell and de Lissovoy.21 It is possible that patients who referred themselves had less severe complaints.20 Unfortunately, the severity of complaints was not measured in the present study. There is evidence, however, that early treatment of musculoskeletal soft tissue injuries by physical therapists produces favorable outcomes in therapeutic effectiveness.22–24 This evidence suggests that timing of physical therapy is essential and that the shorter duration of the complaints of the direct access group may account for the better outcome.
Two major concerns in relation to direct access have been that physical therapists would be overwhelmed by patients referring themselves and that costs for insurers would rise. The present study revealed that, in this first year, the introduction of direct access did not result in an overall increase in the number of patients who received physical therapy. It also appeared that almost 10% of the patients who referred themselves did not receive further treatment after the initial intake. In addition, the patient population in 2006 did not change dramatically compared with the patient population in 2005. Although differences were found, they were too small to be meaningful, and statistical significance was reached due to the large sample size. Our tentative conclusion is that there is not a large "new" group of patients visiting physical therapists. Most of these patients probably would have been referred by their physician had they not accessed physical therapy directly. The consequence of this finding is that GPs probably see fewer patients with complaints of the musculoskeletal system.
The standard GP practice in the Netherlands consists of 2,350 patients, and GPs refer, on average, 72 patients per 1,000 patients a year to physical therapists.25 Calculating with 25% direct access, an average practitioner would refer 42 fewer patients to a physical therapist. Although reduced workload for GPs was seen as one of the advantages of direct access for GPs, this will hardly be noticed by an individual GP. However, it can be estimated that this decrease in patients visiting their GP with complaints of the musculoskeletal system may be cost-effective on a macroeconomic level. The cost-effectiveness on a macroeconomic level of direct access in the Netherlands is one of the factors that were not taken into account in this study and remains to be studied in the future. Several international studies,21,26–29 however, revealed that patients with direct access received fewer prescriptions, were less often referred for a radiograph and for secondary care, and had a decreased need for more invasive treatments. These findings not only have positive implications for patients but also indicate national cost benefits.
Another important issue remains the fear that physical therapists may overlook serious medical conditions. For this reason, Dutch physical therapists specifically focused on detecting relative and absolute contraindications for treatment in their compulsory postgraduate education prior to the introduction of direct access. A study performed by Moore et al30 revealed that patients with direct access were at minimal risk for grossly negligent care when evaluated and managed by physical therapists. It is important to realize, however, that the traditional situation in which treatment by a physical therapist was only possible after referral by a physician, which in most cases was the patient's GP, entailed the risk of the underuse of physical therapy care. International studies have revealed that experienced physical therapists have the same level of knowledge as orthopedists in managing patients with musculoskeletal conditions31,32 and have clinical diagnostic accuracy comparable to that of orthopedic surgeons.32,33 In a study in which patients with orthopedic problems were randomly assigned to a physical therapist or to an orthopedic surgeon, the patients who were seen by an orthopedic surgeon were more likely to have diagnostic imaging and surgery as part of their treatment.26 Therefore, the risks from diagnosis by a physical therapist may not be higher than the risks from more invasive interventions. However, these results cannot be generalized directly to the Dutch situation, and studies on the accuracy of diagnostic decision making by both GPs and physical therapists in the Netherlands are recommended.
Another recommendation is that future research should focus on the communication between GPs and physical therapists. In the Netherlands, GPs traditionally fulfill a role as gatekeepers of the health care system, which makes it important to have a good view of their patients health problems. Therefore, sharing information and collaboration regarding patient care and patient health problems between physical therapists and GPs should be warranted in the patients best interest.
A limitation of the study was that information on the mode of access was missing for a relatively large group of patients, especially in the first 4 months of the study. These patients appeared to be higher educated compared with the group for whom this information was available. Because of this, it is possible that the percentage of patients who made use of direct access was underestimated in the beginning of 2006 because higher-educated patients are more likely to visit a physical therapist without referral. However, for the analyses of the differences in characteristics between patients who referred themselves and patients who were referred by their physician, no bias is expected. Another limitation of the study was that the data in our network came only from physical therapists working on general conditions in general practices. It can be expected that patients with sports injuries are especially inclined to visit a specialized sports physical therapist without a referral because the cause of such a health problem is obvious and there is little reason to suspect underlying pathology. In the future, it would be interesting to include specialized physical therapists, such as therapists who are specialized in sports injuries and manipulative physical therapists, in the network.
