Patient satisfaction reflects the patients' perception of the outcome of care and is being considered for use in future reimbursement schemes. No consensus exists regarding the best instrument to measure patient satisfaction in the field of spine surgery. This systematic review aimed to determine how patient satisfaction for spine surgery has been measured previously and whether a disease-specific, comprehensive instrument to measure patient satisfaction has been established; we also aimed to define the dimensions of care that determine patient satisfaction in spine surgery. A systematic search of three online databases, unpublished sources, and citations was undertaken to identify 156 empirical studies that reported on patient satisfaction in the field of spine surgery. Manuscripts were reviewed in terms of the patient satisfaction instrument used, and the instruments were categorized as per content and method axes. Taxonomy of patient satisfaction with spine surgery identified the major characteristics of providers and medical care that influenced patient satisfaction and acted as a structure to categorically define the dimensions of patient satisfaction in spine surgery. The reviewed studies predominantly used global (108/156) rather than multidimensional (46/156), instruments. Most studies (96.2%) reported satisfaction with outcome rather than with care, and only 18.5% of the studies (29/156) utilized a disease-specific instrument. The following seven dimensions of patient status, outcome, and care experience that affected patient satisfaction were identified: pain, function, patient expectations/preference, specific patient health characteristics, caregiver interpersonal manner, efficacy/clinical outcomes, and postoperative care/therapy. Currently, no disease-specific instrument that includes all dimensions of patient satisfaction in spine surgery has been developed. Such a patient satisfaction instrument should be designed, tested for reliability and validity, and widely implemented.

OBJECTIVE: The diagnosis of glioma remains disheartening in the clinical realm. While a multitude of studies and trials have shown promise, improvements in overall survival have been disappointing. Modeling these tumors in the laboratory setting has become increasingly challenging, given their complex in situ behavior and interactions for therapeutic evasion. Dogs, particularly brachycephalic breeds, are known to spontaneously develop gliomas that resemble human gliomas both clinically and pathophysiologically, making canines with sporadic tumors promising candidates for study. Typically, survival among these dogs is approximately 2 months with palliation alone. METHODS: The authors have completed the first stage of a unique phase I dose-escalating canine clinical trial in which the safety and tolerability of M032, a nonneurovirulent oncolytic herpes simplex virus–1 vector genetically engineered to express interleukin-12, are being studied in pet dogs with gliomas undergoing maximum safe tumor resection and inoculation of the cavity with the viral infusate. RESULTS: Twenty-five canine patients were enrolled between January 2018 and August 2020. One patient was electively withdrawn from the trial by its owner, and 3 did not receive the virus. For the 21 dogs that remained, 13 had high-grade gliomas, 5 had low-grade gliomas, and 3 were undetermined. According to histopathological analysis, 62% of the tumors were oligodendrogliomas. At the time of this report, the median overall survival from the date of treatment was 151 days (± 78 days). No significant adverse events attributable to M032 or dose-limiting toxicities have been observed to date. CONCLUSIONS: In this largest study of oncolytic viral therapy for canine brain tumors to date, treatment with M032 did not cause harm and the combination of surgery and oncolytic viral therapy may have contributed to prolonged survival in pet dogs with spontaneous gliomas. Forthcoming in-depth radiographic, immunohistochemical, and genetic analyses will afford a more advanced understanding of how this treatment impacts these tumors and the immune system. Our goal is to utilize these findings bitranslationally to inform human studies and refine therapies that will improve outcomes in both humans and pet dogs with gliomas.

The objective of the study was to establish how patient satisfaction with surgical treatment of Parkinson's disease (PD) has been previously measured, determine whether an ideal patient satisfaction instrument exists, and to define the dimensions of care that determine patient satisfaction with the surgical treatment of PD. A systematic search of four online databases, unpublished sources, and citations was undertaken to identify 15 studies reporting patient satisfaction with the surgical treatment of PD. Manuscripts were reviewed and instruments were categorized by content and method axes. One study was found to utilize two distinct patient satisfaction instruments, which brought the total number of satisfaction instruments assessed to 16. Major factors influencing patient satisfaction were identified and served as a structure to define the dimensions of patient satisfaction in the surgical treatment of PD. Studies used predominantly multidimensional (10/16), rather than global (6/16) satisfaction instruments. Generic (12/16) rather than disease-specific (4/16) instruments were utilized more frequently. Every study reported on satisfaction with outcome and four studies reported on satisfaction with outcome and care. Six dimensions of patient status, outcome and care experience affecting patient satisfaction were identified: motor function, patient-specific health characteristics, programming/long-term care, surgical considerations, device/hardware, and functional independence. At present, no patient satisfaction instrument exists that is disease-specific and covers all dimensions of patient satisfaction in surgery for PD. For quality improvement, such a disease-specific, comprehensive patient satisfaction instrument should be designed, and, if demonstrated to be reliable and valid, widely implemented.
